Buy S-23 for Sale (S23 SARM)

S23 SARM is currently being studied as an oral male contraceptive. In one study, combined S23 and estradiol benzoate treatment caused infertility in 100% of treated rats. S23 also increased bone mineral density and lean mass in a dose-dependent manner.

Another rat study found that combined S23 and testosterone treatment reversed glucocorticoid-induced muscle atrophy. Glucocorticoids are used as medications to treat inflammation and cancer. Their prolonged or excessive use can cause muscle atrophy.

Research Chems sells S23 SARM for laboratory research use only.


What is S23 SARM?

S23 is a selective androgen receptor modulator (SARM). SARMs are a relatively new class of research chemicals that mimic the activity of testosterone in the body. They are banned for human consumption by the FDA and are prohibited for athletes.

Research has explored the potential use of S23 as an oral male contraceptive. In one rat study, S23 and estradiol benzoate treatment caused infertility in 100% of treated rats. Significantly, the infertility was reversible within 100 days of treatment. [R]

In the same study, S23 increased bone density and stimulated lean muscle gains in a dose-dependent manner. The SARM was also found to reduce fat mass in a dose-related manner. However, none of these effects have been confirmed in humans.

Another rat study found that S23 and testosterone treatment reversed muscle atrophy caused by glucocorticoids. Glucocorticoids are medications for inflammation, allergy, and cancer. Their prolonged or excessive use leads to muscle loss. [R]


How does S23 SARM Work?

S23 SARM works by binding to androgen receptors (ARs) in the muscle and bone tissue. Research has shown that this SARM has a strong binding affinity to ARs in the skeletal muscle, with only partial affinity to androgen receptors in the prostate and seminal vesicles. [R]

Such selective action distinguishes S23 and other SARMs from traditional anabolic steroids. Traditional anabolic steroids are more unrestricted in their action and are more likely to exert unwanted effects on the prostate and other sexual organs in the body. [R]


S23 Research

SR23 has been the subject of several animal studies examining its effects on male fertility, muscle mass, bone density, and fat mass. Here are some key findings:

1) S23 and Male Fertility

In an animal model of male hormonal contraception, either no sperm or very low sperm count in the testes were successfully achieved in animals that received estradiol benzoate plus S-23 treatment. Significantly, a 100% infertility rate was observed in treated animals. [R]

After termination of treatment, serum hormones and mean sperm counts returned to that of control, resulting in 100% pregnancy rates in all treatment groups. These results make S23 SARM a potentially strong candidate for use in oral male contraception. [R]


2) S23 and Lean Muscle Mass

In the above study, the S 23 treatment significantly increased lean muscle and fat mass in male rats. [R]

Another preclinical study suggests that combined Testosterone and S23 treatment may stimulate protein synthesis inhibited by the use of glucocorticoids. Glucocorticoids are medications for inflammation, allergy, and cancer. Their overuse or excessive use inhibits protein synthesis. [R]


3) S23 and Female Sexual Motivation

Menopausal and postmenopausal women can experience a gradual decline in sexual desire, orgasm, and frequency of sex. [R]

A study on postmenopausal rats reported that S23 increased sexual motivation. This SARM was found to be able to increase sexual activity while maintaining the size of the uterus and uterine lining. Similar increases in sexual motivation were observed at doses ranging from 0.5 to 3 mg/kg/day. [R]


4) S23 and Fat Loss

In the animal model of hormonal male contraception, rats treated with estradiol benzoate and S23 were reportedly leaner than control group members.

It was observed that members of the treatment group had a lower percentage of fat mass and lower average weight than their counterparts from the other group. Additionally, a dose-dependent relationship was observed between S23 and fat mass. [R]


5) S23 and Bone Strength

According to an animal study, S23 treatment increased bone mineral density in a dose-related manner. This is potentially significant as low BMD puts you at an elevated risk of fractures, osteoporosis, and other bone-related diseases. [R]


Frequently Asked Questions

What does S23 SARM do?

In animal studies, this SARM has been found to stimulate muscle growth, increase bone mineral density, and induce male infertility. However, no clinical studies have investigated its effects on humans to date.


What is the half-life of S23 SARM?

S23 SARM has a half-life of 11.9 hours. This means that it takes around half a day for the concentration of S23 in the bloodstream to be reduced by half.


Does S23 suppress testosterone?

Animal studies have shown that S23 may deplete testosterone levels in the body.
